RESUMO
[Objective]To investigate the clinical value of computed radiography(CR),computed tomography(CT)and magnetic resonance imaging(MRI)in spinal tuberculosis.[Method]Forty-one patients with histologically confirmed spinal tuberculosis underwant imaging examinations.Forty-one patients were performed CR,22 CT and 31 MRI.[Result]CR of 38 patients clearly revealed bone changes and narrowed or disappeared disk space.CR of 30 patients well showed the abnormal soft tissue.CT scan of 22 patients clearly depicted calcification and no abnormal was found in pedicles in all the 22 CT scans.CT scan of 21 patients revealed bone changes of vertebral bodies and CT scan of 20 patients showed abnormal soft tissue.The soft tissue was involved in all 31 patients with spinal tuberculosis.Diskspaces were involved in 29 cases and the pedicles were normal in all 31 case.The lesions showed hypointense in T1 scan primarily,hyperintense in T2 scan primarily.[Conclusion]CR is the first imaging approach for spinal tuberculosis.CT well reveal the extent and minute calcification.The extent,abnormal soft-tissue and abnormal disk space are more dramatically demonstrated on MRI imaging.CR,in addition to CT and MRI,is helpful in diagnosis of spinaltubereuinsis.
RESUMO
Objective To compare the treatment effect of internal fixation with retrograde interlocking intramedullary nails or condylar plates in the treatment of comminuted fracture of the femoral condyle. Methods 36 cases of comminuted fracture of femoral condyle admitted from 2000 to 2005 were treated with retrograde interlocking intramedullary nails (n=19) or condylar plates (n=17). Union time of fracture and the recovery of knee function were observed respectively. Results The average union time of fracture of the cases treated with retrograde interlocking intramedullary nails was 102 days, and the score of knee function was 84.59. Whereas in the cases treated with condylar plates the union time of fracture was 91.35 days, and the score of knee function was 91.10. Significant differences in both union time of fracture and knee function between the two therapeutic methods were observed (P
